Normalization of Deviation and High-Reliability Organizations

Listen to Mark & Benna Discuss the Normalization of Deviation and High Reliability

I didn’t get the point of the story in the video above. It was about the Normalization of Deviation and Rickover.

I had an interview with Rickover and the last question series he asked was:

Rickover: Midshipman Paradies, are you married?

Me: No sir.

Rickover: Are you engaged?

Me: Yes sir.

Rickover: Has your fiance ever told you you were good looking?

That’s Admiral Rickover standing next to President Jimmy Carter.

Me: (initially baffled by the question from an old man in his mid-70s – thought it was sort of creepy.) Yes, sir.

Rickover: Tell me, what did she mean?

Me: (I was totally thrown off by this line of questioning.) Well, I guess she like the way I looked.

Rickover: Midshipman Paradies, you’re wrong.

Me: Yes, sir. (My best answer of the day.)

Rickover: What she meant was that she wanted to marry you. When you get back, will you ask her what she meant, write me a letter, and tell me what she says?

Me: Yes, sir.

Rickover: Get out of my office.

That’s (in addition to the test and the other interviews) how I got selected for the Nuclear Navy.

But there was still an important step left. I went home, asked my fiance what she meant, and wrote a letter to Rickover telling him what she said.

Why is this important? Rickover’s staff kept track of every commitment that Midshipmen made during their interviews. When I returned for my Engineer’s Exam almost 4 years later, they asked me if I had any outstanding correspondence with the Admiral. I said “No.”

They then looked me up and said, that correct, you wrote your letter to the Admiral.

Why is this important? During his interview, the guy I mentioned in the video (who had been a rule breaker) was questioned about his grades at the Naval Academy. Rickover asked him if he could have done better. He said if he had studied more, he probably could have. Rickover then told him to keep track of his hours in classes, the hours he studied (by topic), and the grades he received, and every week write him a letter with the results. The guy in the story said he would.

When he returned to the Naval Academy, he wrote several letters but stopped before the semester ended. When asked about his outstanding correspondence with the Admiral, he said he didn’t have any. They looked him up and said, according to their records, he still owed Admiral Rickover 20 letters with his study hours and grades. Rickover wanted to know if he would rather write those letters now or explain to the Admiral why responding to an Admiral with the letters was unimportant.

The guy in the story chose the latter – explaining why it was unimportant to complete the correspondence. Before he was done talking to Riickover, he was “de-nuked” and kicked out of the program.

Why was there such an extreme result? Rickover had zero tolerance for Normalization of Deviation. And the guy in the story by his actions (the unwritten letters) and, worse yet, by his choice to tell Rickover why it wasn’t important to correspond with Rickover and their discussion (that didn’t go well) that the guy was likely to deviate from the rules.
